NAPPINGr-MACHINE.

Patented Sept. '7, 1915.

Application filed February 21, 1913. Serial No. 749,790.

To all whom it may concern:

Be it known that I, RICHARD J. STEINER, of the city of Philadelphia and county of Philadelphia and State of Pennsylvania, have invented certain new and useful Tmprovements in Napping-Machines, whereof the following is a specification, reference being had to the accompanying drawings.

The invention relates more particularly in napping machines for brushing or otherwise laying the nap at an inclination to the supporting base, so as togive different shade effects as viewed from opposite points.

An object of the invention is to provide devices for laying the nap in different sections of a pile fabric in opposite directions, whereby the surface as viewed from a com mon point will have varied shade effects.

A further object of the invention is to provide a machine of the above character with steaming devices whereby the finish produced upon the fabric is rendered practically permanent.

These and other objects will in part be obvious and will in part be hereinafter more fully described.

In the drawings which show by way of illustration one embodimentof my invention, Figure I, is a plan view of a napping machine embodying my improvements. Fig. 11, is a side elevation of the same. Fig. 111, is a central longitudinal section taken on the line 111, III, of Fig. I.

The invention broadly consists in providing a supporting frame on which are mounted spaced supporting bars over which the pile fabric is ledsuccessively. The fabric is drawn over thebars at an angle so as to Nap laying devices cooperate with each supporting bar and these nap laying devices are so constructed and operated as to lay the nap in opposite directions in different sections of the fabric and thus give to these sections light and dark shade effects, as viewed from a common point. Referring more in detail to the accompanying drawings, I willfirst describe the main structure and feeding device for'the pile fabric. The operating parts are all mounted on a supporting frame composed of side members 1 and 2, connected by suitable channel cross pieces 3. The lower bars 5, of]

the side members 1 and 2, support bearings .6, in which is journaled the main or driv ng tively.

. shaft 7, upon which are mounted tight and loose pulleys 8 and 9, respectively.

A pulley 10, is also mounted on the main shaft 7. A pulley 12 loose on a stud shaft 13, carried by the side member 1, is driven from the pulley 10, by a belt 11. A. gear 15,

parts movement to a shaft 19, journaled in the mainframe and supporting the feeding roller. 20. The fabric passing through the machine rests on this feeding roller 20, which is so constructed as to frictionally engage the fabric and move the same.

The supporting devices for the fabric which present the same to the nap laying devices, and the nap laying devices will next be described. Paired brackets 21, 21, and 22, 22, are suitably secured to the side members. Bearing blocks 24, 24 and 25, 25, are adjustably mounted in said brackets respec- A shaft 26, is journaledin the bearing blocks 24, and a shaft 27 ,is journaled in the bearing blocks 25. These shafts 26 and 27 support brush rollers 28, and 29, respec tively (see Fig. I). The brushes 30, on these rollers are in sections which are spaced from each other .andthese sections are so disposed as to engage different sections of nap, as the pile fabric passes first under one brush and then under the other. e

The brush rollers aredriven in opposite directions. On the ends of the shafts 26, and 27, are mounted pulleys 32, and 33 respectively. A pulley 37, is'mounted on the main driving shaft 7. A belt 35, passes over the pulleys 32,.and 33. and 37, and also an adjustable idler 38. The belt 35, is crossed at 36, so that the same belt drives the shafts 26.- and 27, in opposite directions.

The fabric-is presented to the nap laying brush roller 1 28, by a supporting bar 49,

having a chamfered side forming a longitudinal straight edge 41. This bar 40, is formed with trunnions 42, and 43, which engage the brackets 21, 21, and constitute pivotal supports therefor. The bar is swung on these trunnions in order ,to move the edge 41, away from the roller to' facilitate the initial insertion of the fabric in the machine. The trunnion 43, extends beyond the bracket 21, and is provided with an operating handle 45, by means of which the bar 40, may be swung asabove noted. The

is secured to the pulley 12, and this gear through the train of gears 16, 17 and 18 imhandle 40, contacts with an adjustablestop screw 46, when the bar is in normal operative position. This stop screw is mounted in a bracket 47, bolted to the side frame 1. By adjusting the screw the straight edge may be set so as to just clear the metallic bristles on the brush roller with which it cooperates. The brush roller can also be vertically adjusted with respect to the bar 40. The brackets 22, 22, also support a straight edge bar 50, which is similar in all respects to the bar lOQand will not need further description. This bar cooperates with the brush roller 29.

The fabric is supported, placed under tension and presented to the supporting bars above described by the following devices. As the fabric passes into the machine it is led over and under tension bars 55, thence under an idle roller 56, and thereafter over the straight edge of the sup porting bar 40. From the supporting bar 40, the fabric passes under the idle roller 57 and thence to the supporting bar 50. After leaving the bar 50, the fabric passes under an idle roller 58, and thence to the feeding roller 20, above described. After passing the feeding roller, the fabric engages an idle roller 59. It will be noted that the idle rollers are so disposed relative to the sup porting bars that the fabric is drawn over the bars at an angle thus bending the fabric and opening the nap at the point where the brush rollers engage the same.

The brushes of the rollers 28, and 29, are made in sections, as above noted and disposed so as to engage different sections of the fabric. The whole surface is, however, acted upon by the two brushes combined. These brushes rotate at high speed relative to the speed of travel of the fabric over the supporting bars and in different directions. The result is that the nap of the pile fabric will be laid at an inclination to the base of thefabric and the sections acted upon by one roller will incline in one direction, while the sections acted upon by the other roller will incline in the opposite direction. The finished or treated fabric will therefore be striped and alternate stripes will have light and dark shade effects respectively, as indicated by the shade lines in Fig. I.

My improved napping machine is of es pecial advantage in carrying out the process set forth in my Patent No. granted August 5th, 1913.

In order to make the finish permanent, I have provided tubes 60 and 61, having slots 62 and 63 therein respectively from which issue steam sprays. These tubes extend across the machine and are supported by the side frames 1 and 2. The steam is supplied by pipes, 65, and 66, and the surplus condensed water is exhausted through pipes 67, and 68, respectively. This steam' treatment of the fabric before the brushing of the nap facilitates the laying of the nap and fixes the same so that the finish impartedto the'pile fabric is practically permanent.

It is obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of my invention as set forth in the appended claims.
